Product Introduction

The Food Grade Safe Leak Proof Square Kraft Paper Meal Box is a square food container specifically designed for food brands that value both packaging aesthetics and practical functionality. As square meal boxes increasingly become the market trend, this product achieves breakthroughs in both leak proof performance and environmental attributes through structural optimization and material upgrades, while maintaining a neat square appearance, meeting modern consumers' expectations for food presentation and safety.

From raw material selection to production molding, this product implements full process quality control. Made from food grade virgin kraft pulp combined with precision molding technology, every meal box possesses stable structural strength. The square design not only facilitates storage and stacking but also conveys a minimalist premium brand visual language through clean lines.

Suitable for various scenarios including light meals, Japanese lunch boxes, Chinese set meals, Western casual dining, healthy meal delivery, home portioning, outdoor picnics, and food exhibitions.

Core Selling Points

Square Design More Efficient Space Utilization

Square meal boxes have inherent advantages in space utilization compared to round ones. This product fully leverages this characteristic:

• Neat Storage Square shape facilitates refrigerator storage and bag organization, stable stacking without wobbling

• Food Compatibility Better suited for block-shaped and strip-shaped foods such as sushi rolls, sandwiches, rice balls, fried pork cutlets

• Clean Visuals Straight line design conveys a minimalist professional brand impression, enhancing overall food presentation

• Space Saving Square boxes occupy less floor space for the same capacity, improving delivery box loading efficiency

Whether exquisite Japanese cuisine or hearty lunch boxes, square containers make food presentation more orderly and appealing.

Food Grade Safety Protecting Every Bite of Freshness

Food safety is the core foundation of takeout packaging. This product maintains strict control from the source:

• Virgin Pulp Made from pure natural virgin kraft pulp, absolutely no recycled pulp added, eliminating secondary contamination risks

• Food Grade Lamination Optional PE lamination or PLA fully biodegradable lamination, compliant with FDA food contact material standards

• Zero Additives Commitment Contains no fluorescent whitening agents, heavy metals, BPA or other harmful substances

• Authoritative Certifications Passed FDA 21 CFR 176.170, SGS, EU 10/2011 and other international tests

Each meal box raw material batch is traceable, giving businesses peace of mind and customers confidence.

Triple Layer Leak Protection Soups Stay Completely Contained

Addressing the pain point of soup-based food delivery, this product features triple layer leak protection design ensuring worry free delivery:

• First Layer Rolled Edge Reinforcement Box rim features thickened rolled edge technology, forming a circular reinforcing structure, enhancing rim rigidity

• Second Layer Double Buckle Interlocking Lid and box body designed with double buckle structure, tightly locked after closing, no loosening with horizontal shaking

• Third Layer Sealing Edge High tensile PET anti-fog lid edge embedded with sealing strip, forming physical seal with box rim

Passing 45-degree tilt, 10-second inversion, and 30-minute vibration simulation tests, all maintaining zero leakage. Teriyaki sauce, curry sauce, miso soup and various other soups stay securely contained.

Eco-Friendly Biodegradable Following Green Consumption

As global plastic ban regulations continue to tighten, eco-friendliness has become a critical question for food brands. This product offers two eco-friendly solutions:

• PE Lamination Version Traditional food grade lamination, excellent waterproof and oil-proof performance, high cost performance, suitable for daily takeout

• PLA Fully Biodegradable Version Corn starch based biomaterial, completely degrades into water and carbon dioxide under industrial composting conditions, no microplastic pollution

Base material selected from FSC certified sustainable forest pulp, ensuring raw material sources environmentally friendly and traceable. Choosing this product is not just regulatory compliance but also conveying brand social responsibility to consumers.

Thickened Material Resists Compression and Softening

Addressing stacking and compression scenarios during delivery, this product uses high grammage thickened kraft paper:

• 300g to 350g grammage, far exceeding ordinary paper boxes on the market

• Holding 100°C hot food for 30 minutes, box remains firm

• Empty boxes stack 10 layers without deformation, filled boxes stack 5 layers without collapse

• Bottom anti-collapse design for even weight distribution, no tilting

Whether heavy curry rice or soup-filled simmered dishes, everything maintains stable shape.

Natural Texture Enhances Food Presentation

Retaining natural kraft paper texture and color, the simple and warm texture perfectly complements various cuisines:

• Japanese Lunch Boxes Natural texture conveys handmade warmth and craftsmanship

• Light Meals Eco-friendly concept perfectly aligns with healthy eating concepts

• Chinese Set Meals Kraft color complements the warm homemade feel of dishes
